Acquired apolipoprotein B deficiency with chronic hepatitis C virus infection.

Chronic hepatitis C virus (HCV) infection is often associated with fatty liver. Apolipoprotein B (ApoB) deficiency is one of the known causes of fatty liver and acquired ApoB deficiency has recently been reported with HCV infection. We report two patients (47-year-old lady and 48-year-old man) who had asymptomatic transaminase elevation, fatty liver, anti-HCV positive with high viral load (genotype 3). Their lipid profile showed low total cholesterol, low-density lipoprotein, triglycerides and ApoB. One of the patients who received treatment for HCV infection showed improvement in lipid profile and ApoB levels.     

Outpatient Initiation of Insulin: A Nurse Practitioner Protocol

Noninsulin dependent diabetes (type II diabetes) is a chronic disease characterized by hyperglycemia. Clients can generally be controlled by diet and exercise or a combination of diet, exercise, and oral hypoglycemic agents. When this therapy is not effective in controlling the hyperglycemia, the health care provider must choose to initiate insulin therapy. Outpatient initiation of insulin is an alternative to hospitalization in the type II diabetic client. Clinical guidelines for the initiation of insulin on an outpatient basis and management of the diabetic client are presented.     

Challenges in geriatric oral health research methodology concerning caregivers of cognitively impaired elderly adults

Little is known about oral health care behaviors of community-dwelling, cognitively impaired elderly (CIE) persons. Few studies have been conducted regarding the actual provision of oral care for CIE persons or the attitudes and concerns about oral health among their caregivers. The CIE person's ability to perform self-care decreases over time, and the role of the caregiver in daily oral care becomes increasingly important. The purpose of this pilot study was to explore the attitudes toward oral health and identify related concerns among caregivers who care for community-dwelling CIE persons. Caregivers were surveyed by means of a self-administered, mailed questionnaire. To maintain confidentiality, an intermediary was used for recruitment and data collection. Overall, 148 caregivers were invited by an intermediary to participate in the survey; only 21 (14%) consented to participate and returned the questionnaire. This paper discusses some of the numerous methodological challenges identified when an attempt was made to survey caregivers' attitudes toward and barriers to providing oral care for a dependent CIE.     

Stability studies of the components of a prototype penicillinase (β-lactamase)-linked ELISA kit

Penicillinase (β-lactamase) enzyme-linked immunosorbent assay (ELISA) for various reproductive hormones developed in the laboratory were found to have wide applicability in the fertility check clinic of the Institute. A need was thought to transform these assays into ready-to-use kit forms. Therefore, prototype ELISA kits for these hormones were developed and stability of the individual component was ascertained at various temperatures (room temperature, 37°C and 2-8°C). Stability studies were conducted on previously validated assay for pregnanediol-3α-glucuronide (PdG). The studies showed that immunosorbents (antibody coated plates) are stable at room temperature for a period of 2 weeks, at 37°C for 1 week and at 2-8°C for a period of 9 months when preserved after treatment with glycerol solution. The lyophilised conjugate, standard and immunoassay buffer, colour reagent, and its substrate were stable at 37°C up to 1 week and at room temperature up to 2 weeks and at 2-8°C for a period of 6 months, during which the stability was studied. © 1993 Wiley-Liss, Inc.
